YARN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 553,392, dated January21, 1896.

Application filed May 9, 1893. Serial No. 473,542. (No model.)

To a whom, it may concern.-

Be it known that I, ALFRED D. CHANDLER, a citizen of the United States,residing at Chelinsford, in the county of Middlesex and Commonwealth ofMassachusetts, have invented a certain new and useful Improvement inYarn-Separators for Spinning-Frames, of which the following is aspecification.

My invention relates to yarn-separators for spinning-frames; and itconsists in the devices and combinations hereinafter described andclaimed, and especially in so constructing and organizing the separatorsthat they may be placed in such a position as not to interfere with theoperation of doffing. Since the introduction of higher speeds forspindles greater effieiency in separators is found necessary, and tomeet this demand the trade has supplied what is technically known as awide blade. These blades have greater width from top to bottom and areusually made to project below their line of support to a greater extentthan above it. The use of these wide blades has made necessaryconsiderable new invention in order to adapt them to existingconditions, and such is the object of my invention, in which I believethis result is first obtained in a satisfactory manner. In my priorpatents, No. 476,731 and No. 496,186, I showed an invention inseparators which obviated some of the defects of prior structures, asthe separators were actuated by separator-rods which relieved thering-rail of the weight of the separator. My former patents, however,did not achieve all that was desired, because the separators thereinshown, if made with wide blades, would in terfere with the operation ofdoffing.

By my present construction and arrangement of the separators and theirsupporting devices, I am enabled for the first time to use separators ofany width desired without interfering in any way with complete ease indotting the spindles or with the construction of other parts of theframe, and by using separators of increased width it is made possible touse a longer traverse of the bobbins and a larger diameter of the samethan has heretofore been customary.

In the accompanying drawings, Figure 11. is a front elevation of suchparts of a ringspinning frame as are necessary for the understanding ofmy invention and my invention applied thereto; Fig. 2, a verticalsection on the line 2 2 in Fig. 1; Fig. 3, a vertical section of thering-rail, the separator-bar, showing in side elevation a spinning-ring,part of a cop of yarn, a separator-rod, its socket, a separator shown byfull lines in its operative position and by dotted lines in the positionit occupies in dofling, and the collar having projections, and thespring which holds said separator in either of its positions; Fig. at, arear elevation of the upper part of the separator-rod, a part of theseparator-bar, the collar having projections, and the spring whichengages said projections to hold the separator in or out of operativeposition; Fig. 5, a side elevation of the parts shown in Fig. 4,thecollar with projections in Figs. i and 5 being in position to hold theseparator between the spindies; Fig. 6, a front GIQVEUJIOH of a part ofthe separator-bar and a separator secured thereto; Fig. '7, a verticalcross-section of the separator-bar and a side elevation of the shank andadjacent parts of a separator secured to said bar; Fig. 8, a rearelevation of the lower part of a separator-rod,the adjustable foot, andthe set-screw by which said foot is held and adjusted on saidseparator-rod; Fig. 9, a side elevation of the parts shown in Fig. 8;Fig. 10, a side elevation of apart of one of the supports of aring-spinning frame, a vertical section of the separator-bar, and a sideelevation of a modified form of the separator secured to said bar, theseparator-blade being repre sented as pivoted to its shank, a part ofthe separator being shown in full lines in its operative position and indotted lines in the position it occupies in the operation of defiing,when its complete backward movement is prevented by the position of thesupport; Fig. 11, a front elevation of part of the separator and part ofthe separator-bar, and Fig. 12 a side elevation of these parts, thesefigures showing another means of accomplishing the object of the deviceshown in Fig. 10 that is, to allow certain of the separators to bestopped by the supports of the spinningframe without interfering withthe complete backward movement of the other separators; Fig. 13, anisometric perspective view of the retaining-spring The roller-beam A,thread-board I3, fingershown in said last-named patent, and the sep-.

arator-rod N is guided in a stand M, which is represented as of the formshown in the patent first above-named, and secured to the guiderail E,as therein shown and described. The separator-bar J instead of being afiat bar or strip, as shown in said patents, is a round bar which turnsdirectly in the socket-piece and dispenses with the hinge-brackets shownin said patent, one side of the separator-bar herein described beingflat to receive the bent shank of the separator I, said shank beingsecured by a screw 4; to said separator-bar.

The separator-bar is prevented from endwise movement in thesocket-pieces L by collars K, which surround said separator-bar betweenthe ends of said bar and said socketpieces, and are held from turning onsaid bar by set-screws it. Each collar K is provided with two lateralprojections k arranged at equal distances from the center of said collarand at about one hundrd and twenty degrees from each other, more orless, one of said projections 70 being immediately below the center ofthe collar when the separators are in operative positions, so that whenthe separator-bar and the collar K are turned to bring the otherprojection k below the center of said collar K the separator will beswung downward and backward into the position indicated by dotted linesin Fig. 3, leaving a clear space between the adjacent bobbins to enablethe bobbins to be doffed without the hand striking the separators. Theseparators are held in their operative positions, as shown by full linesin Fig. 3, or in position for doifing, as shown by the dotted lines insaid figure by a sheet-metal spring U of the form shown in Fig. 13, saidspring having a vertical shank u, provided with a slot to, by means ofwhich it is secured to the side of the socket-piece Lby means of oneormore screws M, as shown in Fig. 5, the upper horizontal part a of saidspring U having a notch, depression or bend w to receive either of theprojections 70 k and to retain the separatorbar and separators inposition. The spring U is in shape similar to a letter U turned on itsside, the shank it being attached to the lower side of the U and formedin one piece therewith. Said separator-bar and separators may easily beturned from one position to the other by the hand applied to theseparators secured to the separator-bar, as above described.

The construction and arrangement of the The separator-' separator bar,separators and connected parts, above described, enable the separatorsto be turned out from between the spindles in spinning-frames in whichthe horizontal distance from the ring-rail to the roller-beam is toosmall to allow of the separators being turned upward sufficiently to beout of the way in the operation of doffing, especially where a very wideseparator-blade is used. The slot u in the shank u of the spring Uallows the spring to be adjusted vertically to vary the pressure of saidspring against the projections 70 as may be necessary.

Where the separators herein described are applied to frames notconstructed with special reference thereto, some one of the separatorsis likely to strike a support S of the frame, and in order that all theseparators may not thereby be prevented from being turned into theposition for doftin g the separators in front of said supports must bemovable with reference to the separator-bar. This end may beaccomplished by forming the shank of the separator in two overlappingparts i" t as shown in Fig. 10, the part i" of said shank being securedto the separator-bar by the means above described, and the part 2' ofsaid shank being pivoted at t to the part i, so that when the separatorsare turned down the separatorblade in striking the support S and beingstopped thereby will turn on the pivot i and allow the separator-barwith other separators to be turned into the position shown by dottedlines in Fig. 3. The part z" of the separator-shank is provided with alaterally-projecting flange or ledge 2 which supports the part 2' ofsaid shank when the separator-bar is turned into operative position.

In Figs. 11 and 12 the separator-shank is all in one piece, but the bentattaching portion of the shank is a longitudinal section of a horizontalcylinder 2' which fits the curved surface of the separator-bar and issecured to said bar, as above described, by a screw 2', but the slot ithrough which said screw passes into the separator-bar, is large enoughand long enough to allow the separators, when stopped by the support S,to turn on said bar, or rather to allow said bar to turn without turningsaid separator and said slot 2' is so arranged that when theseparator-bar is turned back into operative position the screw 2' isturned into and against the upper end of said slot 2' and supports theseparator in its operative position.

The device shown in Fig. 10 is preferred to that shown in Figs. 11 and12, where the former can be used, the latter being intended to be usedin cases where, owing to the nearness of the ring-rail to the tront ofthe roller-beam, the shank of the separator, if the middle of theseparator-blade is properly arranged between the adjacent spindles,would be too short to be conveniently jointed.

Of course, in building new frames, if sufficient attention is paid tothe placing of the spindles and the arrangement of the supports S, allthe separators may be rigidly secured to their separator-bar.

A vertical motion is communicated to the separator-rods N by thecross-shaft arm f, the lower end of said separator-rod being providedwith a foot 0, adjustable on the lower end of said rod by means of aset-screw 0, said foot being provided with a sleeve 0' to receive saidrod and said screw passing radially into said sleeve against said rod.The lower end of the foot 0 is provided with a transverse horizontalslot 0 which receives a stud 0 having a shoulder 0 arranged against thefront of said foot, said stud passing through said slot and beingsecured therein by a nut 0 which turns on the rear end of said studagainst a washer 0", in a well-known manner, so that by loosening thenut 0 said stud 0 may be adjusted in the slot 0 nearer to or fartherfrom the cross-shaft F. An antifriction-roll 0 turns on the stud o infront of the foot 0 and rests upon the cross-shaft arm f, so that whensaid cross-shaft arm is raised the separator-rod and the parts supportedthereby are raised, and when said cross-shaft arm falls saidseparator-rod and supported parts fall by their own gravity, the strainof the separating devices upon said cross-shaft arm being the same atall times.

By adjusting the foot 0 on the separatorrod N the extreme points of thetraverse of the separators will be changed, but the length of saidtraverse will not be affected thereby.

13y moving the stud 0 in the slot 0 nearer to or farther from thecross-shaft F, the length of traverse of the separators will bediminished or increased.

The stopping of a single separator by a support S will not prevent thetwo bobbins next adjacent from being doffed, the one at the right ofsaid separator by the right hand and the other by the left hand.

I claim as my invention- 1. The combination of the separator-bar,separators secured thereto, suitable bearings in which said separatorsmay be turned to bring said separators into operative position or intoposition for dofiing, a collar secured on said bar and havingprojections, and a spring secured to one of said bearings and having abend or depression to receive either of said projections and thereby tohold said separators in either of said positions, as and for the purposespecified.

2. The combination of the frame and its supports, the separator-bar,separators rigidly secured to said bar in front of the space betweensaid supports, suitable bearings in which said bar may be turned, andother separators carried by said bar in front of said supports andadapted to yield in an upward direction only in striking said supports,to allow said first-named separators to be turned downward into saidspace, as and for the purpose specified.

3. The combination of the frame and its supports, the separator-bar,separators rigidly secured to said bar in front of the space betweensaid supports, suitable hearings in which said bar may be turned, andother separators arranged in front of said supports and having shanksformed in two parts, jointed to each other, one part of each shank beingrigidly secured to said separator-bar, to allow said last-namedseparators to yield in an upward direction only in striking saidsupportsand to allow said first-named separators to be turned into said spacebetween said supports, as and for the purpose specified.

4. The combination of the spindles, the ring-rail, the verticalseparator-rod, the separator-bar operated by said rod, separatorssecured to said bar, the cross-shaft having an arm, a foot secured tothe lower end of said separator-rod and having a transverse slot, and astud secured in said slot and raisedby said cross-shaft arm, andadjustable in said slot toward and from said cross-shaft, to vary thelength of traverse of said separator-rod, as and for the purposespecified.

5. The combination of the spindles, the ring-rail, the verticalseparator-rod, the separator-bar operated by said rod, separatorssecured to said bar, the cross-shaft having an arm, a foot secured tothe lower end of said separator-rod and having a transverse slot, a studadjustably secured in said slot and an anti-friction roll carried bysaid stud and resting on said cross-shaft arm, said stud beingadjustable in said slot toward and from said cross-shaft, to vary thelength of traverse of said separator-rod, as and for the purposespecified.
